Title: Drive control device for head for reading recording
Inventor: MIURA KOICHI
IPC: G11B21/02
Filed: 1985-09-19
Abstract: PURPOSE:To attain accurate read/write by fitting a sensor for innermost track. CONSTITUTION:A magnetic head 6 is set to a start position and an outermost circumferential track sensor 9 detecting it generates a start signal of the magnetic head 6 to a control circuit. The control circuit receiving the start signal generates a signal turned by a prescribed angle to a step motor and gives a control signal to the step motor based on the address sequentially just before. When the control signal is given to a track exceeding the innermost position 5' by an error signal or the like, a projection of an index 10 installed to a head carriage 7 passes between a gap between a light emitting element 11a and a photodetector 11b constituting a sensor 11 to shield the light from the light emitting element 11a. The shielding of light is sensed by the photodetector 11b and the signal is fed to the control section to stop the drive of the step motor 2 thereby preventing the movement further inward of the magnetic head 6. Thus, accurate read/write is applied.
